Generators are a fundamental aspect of Python, allowing us to create iterators in a memory-efficient way. Here’s a quick overview of their benefits and usage:
- Memory efficiency: Generators yield one item at a time, so you don’t need to store the whole iterable in memory. - Lazy evaluation: Values are produced only when requested, which can lead to performance improvements, especially with large datasets.
To create a generator, simply define a function using the yield keyword. For example:

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
In many cases, the content resembled that of the marketplaces found on the dark web, a group of hidden websites that are popular among hackers and accessed using specific anonymising software.“We have recently been witnessing a 100 per cent-plus rise in Telegram usage by cybercriminals,” said Tal Samra, cyber threat analyst at Cyberint.The rise in nefarious activity comes as users flocked to the encrypted chat app earlier this year after changes to the privacy policy of Facebook-owned rival WhatsApp prompted many to seek out alternatives.Top Java Quiz Questions ️ from sg
